Chelsea winger Yuri Zhirkov is finding his time on the sidelines 'unbearably hard'. The Russia international has missed the start of theBlues' Premier League campaign because of a knee injury aggravated onthe club's pre-season tour of America. Zhirkov signed at Stamford Bridge from CSKA Moscow for £18million during the summer and is growing increasingly frustrated as the wait to make his competitive debut goes on. He said in the Daily Express: "My knee is still hurting me, but it is better than two weeks ago when it was agony even to step on the foot. "I wish I had a usual kind of injury when I would know exactly that, say, in a month it will all be over. "But when I can't fully comprehend my situation, and even the doctors do not say anything definitively, it is unbearably hard. "My biggest dream now is to wake up one day and realise that the pain in my knee is all but gone." Source: Sky Sports Seems like we wont be seeing Yuri for a while which is shame.
